IMPROVEMENT IN sAws.

Specification forming part of Letters Patent No. 107,808,dated-September 27, 1870.

exact description thereof, lwhich will enable Others skilled in the' artto which my inven. I tionap'pertains to make and use the same, referencebeing` had to the accompanying drawings, forming, part of thisspecification.

Figures 1 and 2 are plan views of the opposite sides 'of my-improvedsaw.

Similar .letters of reference indicate corresponding parts in theseveral figures of the drawings.` Y

My invention has for its Object to provide a circular saw withplaning-bits, for the purpose of planing astrip of lumber as it issawedthat is to say, it shall both saw and plane the lumbersimultaneously.

The invention consists in a series of removable planing-bits and theirholders, in combination with the circular-saw plate, as will behereinafter 'incre fully described.

In the accompanying drawings, A is a circular saw of ordinary orsuitable construction.

B B are planing-bits, stnuck up from the face of the saw in radial linesbetween the perimeter and eye C, as shown in the drawings, with a curvedopening, D, in front of each bit,l for the passage of shavings. The bitsB4 are sharpened to form cutters, and may be struck up to proJect Iromone or both sides of the saw. If desired, when thebits project from oneside of the saw only, adjustable planingirons or bits E may be vemployedin' two or more of the curved vopenings D. These "bits are held inblocks F, attached by rivets G`t'o one side of the saw-plate,- andprovided in their inclined faces H with grooves I, to receive the edgesof the adjustable planing-irons E.

By my invention a circular saw is produced which shall planelumber'while itis sawing the same. If the bits are placed upon one'sideof the saw only, one side of the kerf formed in the lumber will beplaned; but if struck up alternately upon cach side a strip of lumbercan be planed upon both sides as it-is sawedthat is to say, in sawingboards from a log the first board will be planed upon one side only, butboth sides of the saw-kerf will be planed, and consequently when thesucceeding boards are formed they will leavethe saw planed upon bothsides.

1 Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is'- The removable planingsbits E and blocksF, in combination with the crcularsaw plateA, substantially as hereindescribed, vfor the purpose specified.
